Abstract: 本发明涉及卡支付系统。本发明特别涉及一种在动态货币兑换和/或者多元货币方案中用于处理支付卡交易的系统和方法。为了正确地操作，使用了虚像交易。然而，为了防止相对于持卡者的记入借方的款项的重复，不必利用普通交易将这些“虚像副本”交易处理到卡系统中。因此，除了对其相关的结算进行修改之外，还必须修改收单方和/或第三方的主机系统。为了克服这种必然性，本发明提供了一种用于实现在第一商家和第一支付卡持有者之间按第一货币的第一交易金额的支付卡交易的性能的方法。该方法包括步骤：a)创建在第一商家和第二持卡者之间的第一交易金额的第一支付卡交易记录；b)创建在第二商家和第一持卡者之间的第二支付卡交易记录，其中第二交易记录标识了按第二货币的第二交易金额，其等于兑换成第二货币的第一交易金额；以及提交第一交易记录和第二交易记录，用于作为支付卡交易来处理。

Abstract: 1,229,719. Supply systems for strobe flash apparatus. GRAFLEX Inc. 11 Dec., 1969 [6 Jan., 1969], No. 60537/69. Heading H2H. [Also in Divisions G3 and H3] A strobe flash system comprises a push-pull, saturable core, transistor oscillator driven by a battery and operable to charge a storage capacitor through a rectifier. When a certain charge on the capacitor is reached, a switch is actuated to squelch the oscillator by removing bias from its transistors and by shorting a winding of its output transformer. In the circuit shown, storage capacitor 12 is charged through oscillator 10 by battery 11. The transformer 15 of the oscillator produces an approximate square wave output. When a predetermined charge is reached, a neon lamp 25 breaks down and switches on transistors 27, 28 so that a relay 21 is energized. The contact 24 is moved to its normally open position 23 so that forward bias for transistors 13, 14 is removed from resistors 17, 18, and a feedback winding 15c of the transformer 15 is short-circuited. Oscillations thus cease very rapidly and further charging of capacitor 12 is prevented. After discharge of the capacitor, or leakage down to 85-95% of full charge, the lamp 25 will extinguish and reset the relay 21 so that a further charging operation can take place.

Abstract: 1,231,604. Typewriters. U.S.M. CORP. 22 Aug., 1968 [23 Aug., 1967], No. 40167/68. Heading B6F. [Also in Division F2] A control knob assembly for controlling rotation of a platen 10 of a typewriter or the like comprises an axial extension 14 of the platen and, coaxial therewith, a sprocket wheel 20 engageable with a catch device 22 providing a coarse angular location for the platen, a coarse adjustment knob 16 having axially aligned spline teeth 26 formed externally around a circular hub portion 28 thereof, a flexible gear member 30 having around a peripheral portion thereof, a flexible gear member 30 having around a peripheral portion thereof internal spline teeth 32 greater in number than the spline teeth 26 on the coarse adjustment knob 16 and interengaging therewith at circumferentially spaced regions, and a fine adjustment knob 34 having an internal wave generator surface 38, e.g. of elliptical form, surrounding at least the peripheral portions of the flexible gear member 30 for maintaining the tooth interengagement and for circumferentially progressing the regions of engagement when the fine adjustment knob 34 is rotated, either the coarse adjustment knob or the flexible gear member being connected to the sprocket wheel. As shown, the coarse adjustment knob 16 and the sprocket wheel 20 are integrally formed and fit freely over the extension 14. The flexible gear member 30 is keyed to the extension 14 by corresponding flat surfaces 18, 31. On rotation of the coarse adjustment knob 16, the flexible gear member 30 is rotated owing to the tooth interengagement, and the platen is thereby rotated through the extension 14. Or rotation of the fine adjustment knob 34, the major axis of the elliptical wave generator surface 38 rotates, so causing the regions of tooth interengagement to rotate accordingly. Since the knob 16 and gear member 30 bear different numbers of teeth, slow relative rotation occurs therebetween, the gear member and hence the platen being rotated owing to the catch device 22 preventing rotation of the knob 16. A resilient circular insert 40 of coiled wire stiffens the wave generator surface and prevents axial separation of the knobs 16, 34. In an alternative embodiment (Figs. 3, 4, not shown), the flexible gear member (72) is fixed to the sprocket wheel (60) and is freely rotatable on the platen extension (52), and the coarse adjustment knob (50) is keyed to the extension (52). The fine adjustment knob (64) projects through a slot in a cover (58) housing the sprocket wheel, catch (62), flexible gear member and coarse adjustment knob hub (78). The parts of the control knob assembly may be moulded from plastics material. The wave generator surface may have three or more lobes instead of the two of the elliptical surface shown.

Abstract: 1,232,092. Radio-active borehole logging. PAN GEO ATLAS CORP. July 9, 1968 [July 10, 1967], No.32683/68. Heading G1A. The invention relates to a borehole logger of the type that is compensated for mud cake on or rugosity of the borehole walls by having two detectors at different spacings from a source of radiation and deriving a correction signal from the outputs of the detectors. The invention provides means for making the correction signal non- linear to improve correction. Downhole construction A pad, Fig. 2, containing a gamma ray source 24 and short and long spacing detectors 26, 28 is retractably held against the borehole wall by arms 14, 16 extending from a central unit. A 1/16" -1/8" layer of lead is located in front of detector 26 to increase its sensitivity to the near mud cake at the expense of sensitivity to more distant formations. A spring 52 keeps the source end of the pad pressed against the borehole wall. Alternatively a cable 60 attached to the lower part of the pad may be used. Circuit arrangement To produce a formation density log, the detectors 26, 28 are connected to respective rate meters 82, 80, Fig. 3, and logarithmic amplifiers 90, 86. The long spacing detector signal is inverted by amplifier 94 and added to the short spacing detector signal at the input to amplifier 98. The output of amplifier 98 across resistor 104 is the correction signal ## which is added to the long spacing signal in amplifier 106 to give a corrected density signal # B  across resistor 108. Amplifier 98 has a feedback circuit, the feedback of which decreases with increasing output whereby the output varies with more than the first power of the input. Both ## and # B  are recorded by separate galvanometers. In a modification Fig. 4, (not shown) the non-linearity is introduced by adding to the correction signal a voltage tapped off from a potentiometer by an arm driven by the correction signal. Calibration A calibration jig 110, Fig. 5, comprises two gamma ray sources spaced apart by the separation of detectors 26, 28 in a housing provided with lead screens 113, 115, 117, 119, 121, slide 116, carrying absorbers 130, 132 and an absorbing slide 122. With the absorbers removed by the slides potentiometers 84, 88 are adjusted to give a predetermined reading of p B . Slide 116 is then moved to insert absorbers 124, 126 to simulate an increase in formation density and potentiometer 100 is adjusted to give a new predetermined reading of p B . Finally slide 122 is inserted between source 112 and detector 26 to simulate a known mud cake thickness and formation density, and potentiometer 102 is adjusted until a predetermined # B  is obtained.
